Be it known that l, RALPH W. Harms, a

citizen of the United States, residing at Crani'ord, in the county ofUnion and State 'or" New Jersey, have invented a new and usefulHeadlight, of which the following is a specification. p Thisinvention-relates to head lamps and more particularlyto headlamps-especially designed for use on motor vehicle or the like.

' The primary to provide novel light rays projected from the lamp, noteblinding of persons moving towards the lamp. U Another object of theinventioniis to pro vide novel means for adjusting the lamp object ofthe invention is. means for deflecting the with respect to the bodyportion or reflectors, thereof to facilitate the focusing of the v,w'ill-be reflected onto the reflector 8.

lileferring to the drawings in detail, the reference character 5designates the body" portion of the lamp casing, which is of the usuaiconstruction, the same being formed with a flange 6 providing a supportfor the lens i". I

Positioned within the casing 5 is t rel-lecto elinn- With the foregoingand other objectsin through a lamp constructed In accordance with; thepresent invention,

tor 8, which is also curved to conform to the curvature of the lampcasing, the reflector being however spaced from the inner surface of thecasing 5. The lamp support includes a tubular body portion 9 throughwhich the wires 10 extend, which wires have connection with a suitablesource of electric supply not shown, for supplying electric current tothe rods 11, which provide the su port for the reflector 12 and'bulb 13.

from the rods 11 to prevent short circuiting. This'socket member issecured to the bar 14 as by means of the screw 16 which socket memberalso has connection. with the re- .tlector-12 that has its concavedsurface facas 'ositioned on the rods 11. is a fibre bar-14; vdesigned toinsulate the socket member 15 ing the 'concaved surface of the reflector8,

so" that the light rays projected from the lamp 13 supported by thesocket member 15 A contact member 19 is secured to the bar 14: and hasone end thereof. contacting with one of the rods 11, while the oppositeend of the contact member engages the socket membfi! 15;

The contact member 20 is also supported on the bar Pi and has its innerend engaging the-contact end 21 of the socket member 15, the oppositeend of the contact member being curved. and contacting with the oppositerod 11 completing the circuit to the socket l5, and lamps supportedthereby.

it might be further stated that the connection between the bar 14 androds 11, is such as to create a binding action therebetween, causing thebar 14 to be frictionally held in various positions of adjustment alongthe rods 11. j l

The reflector 12 is'formed with openings at points adjacent to theperiphery thereof, which openings accommodate the rods 11, a suitableinsulating material 28 being positioned in the openings, to insulate theretiector 12 from the rods.

Thus it will be seen that by moving the bar 14 and lamp supportedthereby, towards and away from the main reflector 8, the lamp may beproperly focused. The outer ends of the rods 11 are connected as bymeans of the fibrous bar 22, as clearly shown by Figure 1 of thedrawings. it is ccnteznplatedto provide lamp supporting structure whichmay berendil and easily positioned in the usual lamp soc acts so thatthe rods 11 will be disposed in horizontal parallel relation with eachother, and to this end, I have provided a novel form of adjustable plug.

This plug is indicated at 23 and is formed with a recessed portion toaccommodate the sleeve 24: that carries the laterally extending pins 2%that move in the usual bayonet slots of a lamp socket. As shown, theends of the rods 11 extend into the plug 23, the end of one rodextending beyond one end of the pin 23, where the same extends at rightang es to provide a contact member 25. A lock washer 26 is positionedover one end of the plug, and held thereon by means of screws 29 andengages the sleeve 24 to hold the same in its adjusted position, therebeing provided a lug 27 on the washer 26 that con tacts with the undersurface of the member 25 to set up a binding action between the washerand sleeve 24.

From the foregoing it will be seen that should it be desired to move thepins 24 to permit the bars 11 to be supported in horia zontal parallelrelation with each other, the washer 26 may be removed and the sleeve 24rotated on the plug to bring the pins in proper relation with thebayonet openings in which the plug is positioned. The washer 26 is nowreplaced to hold the collar in such adjusted position.

Having thus described the invention, what is claimed as new is 1- 1. Ina device of the character described, a lamp casing, a reflectorsupported within the lamp casing, a lamp supporting member includingrods disposed in parallel relation with each other, an insulating barmovable on the rods and carrying a lamp socket, means contacting withthe rods for supplying electric current to the lamp socket, and saidinsulating bar adapted to be adjusted along the rods to adjust the lampsupported thereby, with respect to the reflector.

2. In a device of the character described, a lamp casing, a reflectorwithin the lamp casing, supporting rods within the lamp casing, aninsulating bar connecting the rods,

said insulating bar adapted to be moved longitudinally of the rods, abulb and reflector supported by the bar, means carried by the bar forcompleting a circuit to the lamp, and said bar adapted to be moved lonitudinally of the rod to adjust the same wit- 1 respect to the firstmentioned reflector. 3. In a device of the character described, a lampcasing, said casing having a central plug opening, a reflector withinthe casing, supporting rods, an adjustable lamp supportin r meansmovable on the rods, a lamp and ref ector mounted on the adjustable lampsupporting means, an adjustable plug, said rods having their endsdisposed within the adjustable plug, and said plug adapted to bepositioned within the socket member.

a. In a device of the character described, a lamp casing, supportingrods positioned within the casing, a plug connecting the inner ends ofthe supporting rod, an adjustable lamp supporting member movable contactmembers on the movable bar and engaging the supporting rods to receiveelectric current therefrom, and said movable bar adapted to be movedwith stationary bar.

In testimony that I claim the foregoing as my own I have hereto aflixedmy sigmature. I
